Infiniti Q50
The compact executive saloon, and mechanically a Nissan Skyline — the same VQ or VR engines, the same platform, the same faults. Searching under the Nissan name is usually the shortest route to information. Its steer-by-wire system on some versions is the genuinely unusual part: there is no permanent mechanical link between wheel and rack, so a steering fault there is an electronic diagnosis with a mechanical backup clutch behind it.

The G35 and G37 the Q50 renamed; VQ35 and VQ37 on the FM platform, so 350Z and 370Z information applies to the driveline.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
